Title: Sterilization method
Inventor: ARA TADAHIKO
IPC: C02F1/461
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To provide the method for sterilizing various kinds of water such as bath water of 24hr bath. SOLUTION: The sterilization of the water is executed by allowing a direct current or a low-frequency alternate current to flow to electrodes placed in a fluidizing or fluidized water in a voltage less than a decomposition voltage of the water. A deposited matter on the electrodes is rapidly diffused into the water to progress electrolysis by placing the electrodes in the fluidizing waste water, and also the electrolysis is not proceeded more than a diffusion amount of the deposited matter by keeping the voltage in less than the decomposition voltage. As a result, a use of a useless energy is few.  A nascent oxygen generated on a surface of an anode by the electrolysis of the water is liable to contact with bacteria in the water since the water is fluidizing, and in the case when the oxygen is brought into contact with the bacteria, a cell membrane of the bacteria is destroyed and died. And this method is a purifying and deodorizing effect of the water since the nascent oxygen has a function decomposing an org. matter.

Filed: 1989-04-21
Abstract: PURPOSE:To protect an inner circuit from malfunction by a method wherein a switching element is provided between a power source wire and an electrostatically protective element. CONSTITUTION:When a high voltage is applied between an external connection terminal 3 and a power source wire 1, the high voltage is applied to the base of a switching element 7-1 through the intermediary of a switching element 7-2 which is in an ON- state to turn the switching element 7-1 ON. Then, a voltage is applied to an electrostatically protective element 4 almost concurrently when the switching element 7-1 is turned ON. At this point, as a voltage is applied to the forward side of the diode of the element 4, a current path is established between the external terminal 3 and the power source wire 1. By this setup, the voltage between the external terminal 3 and the power source wire 1 is clamped down to a voltage of 0.7-1V or the forward voltage of the diode. On the other hand, when a voltage is applied to the external connection terminal 3 at the time when a power source voltage is not applied, as the switching element 7-2 is in an OFF-state, the switching element 7-1 is also in an OFF-state, so that a current path is not established between the external power wire 1 and the external connection terminal 3 and concurrently an LSI to which a power is not supplied hardly malfunctions.

Abstract: PURPOSE:To enable detection of particles in a liquid within a small tube that is hard to measure with an ordinary detector, by arranging one polarization plane maintaining optical fiber and a 1/4 wavelength plate to make an irradiation light and a reflection scattered light orthogonal to each other in the polarization. CONSTITUTION:A linearly polarized light 11 emitted from a light source 7 is made incident into a polarization plane maintaining optical fiber 1 so as to coincide with one propagable polarized light thereof 1. Light passing through the optical fiber 1 is focused with a Selfoc lens 2 and turned to a circularly polarized light with a 1/4 wavelength plate 3 to irradiate fine particles 16 in a liquid. The circularly polarized light scattered back by the fine particles 16 passes through the 1/4 wavelength plate 3 again to be turned to a linearly polarized light orthogonal to the irradiation light, which then, is propagated through the optical fiber 1 via the lens 2, reflected with a polaroid prism 6 and received with a photodetector 8 to be converted into an electrical signal. Here, the lens 2, the 1/4 wavelength plate 3 and the optical fiber 1 are covered with a movable protective cover 4.
